(iii) “Effective Date” means any date as of which any part of such registration statement or any post-effective amendment thereto relating to the Units became, or is deemed to have become, effective under the Securities Act in accordance with the Rules and Regulations;

(iv) “Issuer Free Writing Prospectus” means each “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) prepared by or on behalf of the Partnership or used or referred to by the Partnership in connection with the offering of the Units;

(v) “Preliminary Prospectus” means any preliminary prospectus relating to the Units, including the Base Prospectus and any preliminary prospectus supplement thereto, included in such registration statement or filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations;

(vi) “Pricing Disclosure Package” means, as of the Applicable Time, the most recent Preliminary Prospectus, if any, together with (A) each Issuer Free Writing Prospectus filed or used by the Partnership on or before the Applicable Time and identified on Schedule 2A attached hereto, other than a road show that is an Issuer Free Writing Prospectus but is not required to be filed under Rule 433 of the Rules and Regulations, and (B) the information included on Schedule 2B attached hereto;

Any reference to the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus shall be deemed to refer to and include any documents incorporated by reference therein pursuant to Form S-3 under the Securities Act. Any reference to the “most recent Preliminary Prospectus” shall be deemed to refer to the latest Preliminary Prospectus included in the Registration

The Registration Statement did not, as of the Effective Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Registration Statement in reliance upon and in conformity with written information furnished to the Partnership by the Representatives on behalf of any Underwriter specifically for inclusion therein, which information is specified in Section 8(e) hereof.

(k) Subsequent to the execution and delivery of this Agreement (i) neither the Partnership nor any of its subsidiaries shall have sustained any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree or (ii) there shall not have been any adverse change in the equity or long-term debt of the Partnership or any of its subsidiaries or any adverse change, or any development involving a prospective adverse change, in or affecting the condition (financial or otherwise), results of operations, unitholders’ equity, properties, management, business or prospects of the Partnership and its subsidiaries taken as a whole, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus.

8. Indemnification and Contribution.

(a) The General Partner and the Partnership, jointly and severally, shall indemnify and hold harmless each Underwriter, its directors, officers, employees and agents of each Underwriter, affiliates of any Underwriter who have, or who are alleged to have, participated in the distribution of the Units as underwriters, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Units), to which such Underwriter or such director, officer, employee, agent, affiliate or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, taken together with the Pricing Disclosure Package, or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) used or referred to by any Underwriter, taken together with the Pricing Disclosure Package, (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus,

any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information (in the case of either an Issuer Free Writing Prospectus or any Permitted Issuer Information, taken together with the Pricing Disclosure Package) any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Units or the offering contemplated hereby, and that is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the General Partner and the Partnership shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each Underwriter and each such director, officer, employee, agent, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably incurred by such Underwriter, or such director, officer, employee, agent or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the General Partner and the Partnership shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information in reliance upon and in conformity with written information concerning such Underwriter furnished to the Partnership by the Representatives on behalf of such Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability that the General Partner or the Partnership may otherwise have to any Underwriter or to any director, officer, employee, agent, affiliate or controlling person of such Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the General Partner, the Partnership, their respective directors, officers, employees, agents and each person, if any, who controls the General Partner or the Partnership within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the General Partner, the Partnership or any such director, officer, employee, agent, or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and

in conformity with written information concerning such Underwriter furnished to the Partnership by the Representatives on behalf of such Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the General Partner, the Partnership or any such director, officer, employee, agent or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under Section 8(a) or 8(b), notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under Section 8(a) or 8(b) except to the extent it has been materially prejudiced by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of the indemnifying party’s election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party, the other indemnified parties and their respective directors, officers, employees, agents and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnifying party and the indemnified party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees, agents and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees, agents or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding

and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such claim, action, suit or proceeding effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such claim, action, suit or proceeding, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Sections 8(a) or 8(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the General Partner and the Partnership, on the one hand, and the Underwriters, on the other, from the offering of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the General Partner and the Partnership, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the General Partner and the Partnership, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Firm Units purchased under this Agreement (before deducting expenses) received by the Partnership (as set forth in the table on the cover page of the Prospectus) bear to the total underwriting discounts and commissions received by the Underwriters with respect to the Firm Units purchased under this Agreement (as set forth in the table on the cover page of the Prospectus). The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the General Partner, the Partnership or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The General Partner, the Partnership and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Units exceeds the amount of any damages that such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of

fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint. No party shall be liable for contribution under this subsection (d) except to the extent and under such circumstances as such party would have been liable for indemnification under this Section 8 if such indemnification were available or enforceable under applicable law.

(e) Each Underwriter severally confirms that (i)(A) the public offering price and (B) the statements regarding delivery of the Units by the Underwriters, in each case set forth on the cover page of the Prospectus, and (ii)(A) the table setting forth the name of, and the number of Firm Units to be purchased by, each Underwriter, (B) the concession figure and (C) the paragraph relating to stabilization by the Underwriters, in each case appearing under the caption “Underwriting” in the Prospectus, will be correct. Each Underwriter severally confirms and the General Partner and the Partnership acknowledge and agree that such information will constitute the only information concerning the Underwriters furnished in writing to the Partnership by the Representatives on behalf of the Underwriters specifically for inclusion in the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

9. Defaulting Underwriters. If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the non-defaulting Underwriter(s) shall be obligated to purchase the Units that the defaulting Underwriter(s) agreed but failed to purchase on the Delivery Date in the respective proportions that the number of the Firm Units set forth opposite the name of each non-defaulting Underwriter in Schedule 1 attached hereto bears to the total number of Firm Units set forth opposite the names of the non-defaulting Underwriter in Schedule 1 attached hereto; provided, however, that the remaining non-defaulting Underwriter(s) shall not be obligated to purchase any of the Units on the Delivery Date if the total number of Units that the defaulting Underwriter(s) agreed but failed to purchase on the Delivery Date exceeds 9.09% of the total number of Units to be purchased on the Delivery Date, and no non-defaulting Underwriter shall be obligated to purchase more than 110% of the number of Units that it agreed to purchase on the Delivery Date pursuant to the terms of Section 2 hereof. If the foregoing maximums are exceeded, the non-defaulting Underwriter(s), or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Units to be purchased on the Delivery Date. If the non-defaulting Underwriter(s) or other underwriters satisfactory to Representatives do not elect to purchase the Units that the defaulting Underwriter(s) agreed but failed to purchase on the Delivery Date, this Agreement (or, with respect to any Option Unit Delivery Date, the obligation of the Underwriters to purchase, and of the Partnership to sell, the Option Units) shall terminate without liability on the part of the non-defaulting Underwriter(s), the Partnership or the General Partner, except that the Partnership will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11 hereof. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 attached hereto that, pursuant to this Section 9, purchases Units that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership or the General Partner for damages caused by its default. If other Underwriters are obligated or agree to purchase the Units of a defaulting or withdrawing Underwriter, either the Underwriters or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the judgment of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives on behalf of the Underwriters by notice given to and received by the Partnership prior to delivery of and payment for the Units if, prior to that time, any of the events described in Section 7(k), (l) or (m) hereof shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.

11. Reimbursement of the Underwriters’ Expenses. If the Partnership shall fail to tender the Units for delivery to the Underwriters for any reason or the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement, the General Partner and the Partnership will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Units, and upon demand the General Partner and the Partnership shall pay the full amount thereof to the Underwriters.

12. Research Analyst Independence. The General Partner and the Partnership acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of their respective investment banking divisions. The General Partner and the Partnership hereby waive and release, to the fullest extent permitted by law, any claims that the General Partner or the Partnership may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the General Partner or the Partnership by the Underwriters’ investment banking divisions. The General Partner and the Partnership acknowledge that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Partnership and its subsidiaries.

13. No Fiduciary Obligation. The General Partner and the Partnership acknowledge and agree that in connection with this offering, the sale of the Units or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the General Partner, the Partnership or any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to either the General Partner or the Partnership, including, without limitation, with

respect to the determination of the public offering price of the Units, and such relationship between the General Partner and the Partnership, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the General Partner or the Partnership shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the General Partner and the Partnership. The General Partner and the Partnership hereby waive any claims that the General Partner or the Partnership may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

14. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Underwriters, shall be delivered or sent by mail or facsimile transmission to Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Syndicate Registration (Fax: 000-000-0000), with a copy, in the case of any notice pursuant to Section 8(c) hereof, to the Director of Litigation, Office of the General Counsel, Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, and to the Citigroup Global Markets Inc.

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof.

15. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the several Underwriters, the General Partner, the Partnership, and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the General Partner and the Partnership contained in this Agreement shall also be deemed to be for the benefit of the directors, officers, employees and agents of the Underwriters and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act and (B) the indemnity agreement of the Underwriters contained in Section 8(b) hereof shall also be deemed to be for the benefit of the directors of the General Partner, the officers of the General Partner who signed the Registration Statement and each person, if any, who controls the General Partner or the Partnership within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

16. Survival. The respective indemnities, representations, warranties and agreements of the General Partner, the Partnership and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of units representing limited partner interests (the “LP Units”) of Buckeye Partners, L.P., a Delaware limited partnership (the “Partnership”) from the Partnership, and that the Underwriters propose to reoffer the LP Units to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital, Inc. on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any LP Units (including, without limitation, LP Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and LP Units that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for LP Units, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of LP Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of LP Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any LP Units or securities convertible into or exercisable or exchangeable for LP Units or any other securities of the Partnership, with the exceptions of registration statements with respect to (i) the LP Units and Class B Units issued to Vopak Bahamas, N.V. pursuant to a Registration Rights Agreement dated February 15, 2011 and (ii) any Class B Units issued to the holders of Class B Units as payment-in-kind in lieu of cash distributions, or (4) publicly disclose the intention to do any of the foregoing, for a period

Exhibit A — Page 1

commencing on the date hereof and ending on the 60^th day after the date of the Prospectus relating to the Offering (such 60-day period, the “Lock-Up Period”).

The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Letter Agreement during the period from the date of this Lock-Up Letter Agreement to and including the 34th day following the expiration of the Lock-Up Period, he will give notice thereof to the Partnership and will not consummate such transaction or take any such action unless he has received written confirmation from the Partnership that the Lock-Up Period (as such may have been extended pursuant to this paragraph) has expired.

The foregoing limitations shall not apply to (a) transactions relating to LP Units or other securities acquired in open market transactions after the completion of the Offering, provided that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with subsequent sales of LP Units or other securities acquired in such open market transactions, (b) transfers of LP Units or any security convertible into LP Units as a bona fide gift, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with such bona fide gifts, (c) with respect to Buckeye Pipe Line Services Company, a Pennsylvania corporation (“Services Company”), LP Units sold in connection with (i) the liquidation of employee accounts in the Buckeye Pipe Line Services Company Employee Stock Ownership Plan (“ESOP”) at or about the time an employee ceases to be an employee of Services Company, (ii) the exercise by ESOP participants of an option, available to all ESOP participants, to diversify up to 25% of their accounts annually or (iii) the exercise by ESOP participants who are 55 years old or older to diversify a portion of their accounts in accordance with IRS diversification regulations, or (d) distributions of LP Units or any security convertible into LP Units to limited partners or stockholders of the undersigned; provided that in the case of any transfer or distribution pursuant to clause (b) or, other than for Services Company, (d), each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter.

In furtherance of the foregoing, the Partnership and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Partnership notifies the Underwriters that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the LP Units, the undersigned will be released from his obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Partnership and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership and the Underwriters.

(bb) To our knowledge, except as disclosed in the Registration Statement, the Prospectus or the Pricing Disclosure Package, no person has the right to require the registration under the Securities Act of any securities of the Partnership or to include any such securities in the Registration Statement or the offering contemplated by the Underwriting Agreement, whether as a result of the filing or effectiveness of the Registration Statement or the sale of the [Firm/Option] Units as contemplated by the Underwriting Agreement or otherwise.

(dd) Each document filed pursuant to the Exchange Act and incorporated by reference in the Registration Statement and the Prospectus (except for the financial statements and financial schedules and accounting information and other financial and accounting data included therein, as to which we express no opinion) appeared on its face to be appropriately responsive as of its filing date as to form in all material respects to the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder; the Registration Statement, as of the time of its most recent effectiveness, and the Prospectus, as of its date, (except for the financial statements and financial schedules and accounting information and other

Exhibit B — Page 6

(ee) The Underwriting Agreement has been duly authorized, executed and delivered by each of the General Partner, individually, and the General Partner on behalf of the Partnership.

(ff) The Partnership has all requisite limited partnership power and authority to issue, sell and deliver the [Firm/Option] Units in accordance with and upon the terms and conditions set forth in the Underwriting Agreement, the Partnership Agreement, the Registration Statement, the Pricing Disclosure Package and the Prospectus, and to consummate the transactions contemplated by the Underwriting Agreement. At such Delivery Date, all partnership or limited liability company action required to be taken by the Partnership, any of its unitholders or any of the Partnership Entities for the execution and delivery of the Underwriting Agreement and the consummation of the transactions contemplated by the Underwriting Agreement shall have been validly taken.

In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the federal laws of the United States of America, the laws of the State of New York, the Delaware Revised Uniform Limited Partnership Act and the Delaware Limited Liability Company Act.
